Abstract
In the exemplary embodiment the temperature-dependent resistance of the cathode coil is taken as the measure of the instantaneous coil temperature and is employed for the purpose of dimensioning an increased filament power in the transition time between fluoroscopy and radiography, or for the purpose of dimensioning a heating pause in the transition time between radiography and fluoroscopy, respectively.
